This sound is a generic “USA” crowd chant rather than a clip tied to one confirmed movie or TV source. Similar chants have long been common at American sports events, campaign rallies, and public gatherings, which is why the audio is so recognizable online. In short-form videos and memes, creators use it as a quick signal for nationalism, team pride, or exaggerated American energy. It also gets paired with the eagle rahhh style of patriotic joke edits because both sounds communicate the same overblown mood fast.
